{"cve":"CVE-2019-18683","nvd":{"published":"2019-11-04T16:15:11.327","modified":"2026-06-17T02:25:17.680","status":"Modified","description":"An issue was discovered in drivers/media/platform/vivid in the Linux kernel through 5.3.8. It is exploitable for privilege escalation on some Linux distributions where local users have /dev/video0 access, but only if the driver happens to be loaded. There are multiple race conditions during streaming stopping in this driver (part of the V4L2 subsystem). These issues are caused by wrong mutex locking in vivid_stop_generating_vid_cap(), vivid_stop_generating_vid_out(), sdr_cap_stop_streaming(), and the corresponding kthreads. At least one of these race conditions leads to a use-after-free.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H","score":7.0},"cwes":["CWE-362","CWE-416"],"references":["http://lists.opensuse.org/opensuse-security-announce/2019-12/msg00029.html","http://packetstormsecurity.com/files/155890/Slackware-Security-Advisory-Slackware-14.2-kernel-Updates.html","http://www.openwall.com/lists/oss-security/2019/11/05/1","https://lists.debian.org/debian-lts-announce/2020/03/msg00001.html","https://lore.kernel.org/lkml/20191103221719.27118-1-alex.popov%40linux.com/"],"products":["broadcom:fabric_operating_system","canonical:ubuntu_linux","debian:debian_linux","linux:linux_kernel","netapp:8300_firmware","netapp:8700_firmware","netapp:a400_firmware","netapp:a700s_firmware","netapp:active_iq_unified_manager","netapp:cloud_backup","netapp:data_availability_services","netapp:e-series_santricity_os_controller","netapp:element_software","netapp:h610s_firmware","netapp:hci_management_node","netapp:solidfire","netapp:steelstore_cloud_integrated_storage","opensuse:leap"],"source":"nvd","synced_at":"2026-10-19T20:59:25.448946135+00:00"},"epss":{"cve":"CVE-2019-18683","score":0.00994,"percentile":0.6263,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
